The Boardwalk View rooms are about 20% of the resort. The Standard view rooms are about another 20%. Preferred View at the Boardwalk is a misnomer, I'm not sure if anyone would rather have a preferred view if a Boardwalk View or Standard View is available. Which means once the resort is 40% full, its unlikely to get one of those views. Which doesn't mean its impossible - at that time of year is a good time to try.
60% of the resort is preferred view - those rooms are generally available at seven months - with the exception of December when the resort often books completely full before the seven month window, and F&W, when there are often rooms available RIGHT at the seven month window and they are often gone the day the window opens (although sometimes people get lucky).
